Product Name: calcium aluminate
Details: calcium aluminate is a gray white powder. The main ingredient is a mixture of calcium aluminate (CaO. 2A1203) and calcium aluminate (CaO. A1203). It is dissolved in water, the water solution is alkaline, and the pH value is about 11.
The activity of calcium aluminate and inorganic strong acid is very high, and can be started at normal temperature. Heat and rapid temperature rise, alumina leaching rate can reach over 90%, and use it to produce liquid or solid aluminum chloride can simplify the process, reduce the cost, improve the quality of products, raw materials at home and abroad, the majority of polyaluminium chloride is used by manufacturers of.
Calcium aluminate is mainly used in the production of polyaluminum chloride, aluminum sulfate, sodium aluminate and other aluminum salts. It can also be used for the adjustment of the degree of alkalinity, and can also be used in refractory materials.
At present, there is no unified quality standard in our country, its production inspection and so on are carried out according to our O / GWDGS001 - 1999 standard.
The reaction of calcium aluminate with hydrochloric acid can produce polyaluminum chloride in one step. The mixture ratio press formula is calculated.

Alumina content% in Aal2O3 - calcium aluminate
Oxidation content% in AcaO - calcium aluminate
Hydrogen chloride content% in Ahc1- hydrochloric acid
N -% dissolution rate
In production, first add the water in the reaction tank and open the mixing slurry. Then add the hydrochloric acid quantitatively, then dilute it to the required concentration, then slowly add calcium aluminate to react. In the process of reaction, the temperature in the pool will increase gradually. When more than 110 degrees centigrade, a proper amount of water can be suppressed. Make up a small amount of water. Keep the normal temperature. After the calcium aluminate, and then reaction for 2 hours, more than 3 test paper PH, can be diluted with water to a density of 1.25 - 1, 26, discharge to the sedimentation tank after precipitation, the supernatant for liquid products, but also in the dryer, solid polymeric aluminum chloride products.
Transportation, packaging and storage:
The company's products are packed in plastic woven bags with net weight of 50+1Kg
Transportation and storage should be kept dry. Waterproof, moisture-proof. In case of water blocking, shall be treated with.
